So me and ChatGPT found out that Hyper-V tanks perfomance and GPU / CPU Usage.

FIXED: Battlefield 6 stuttering / poor performance on Ryzen 7950X3D — caused by Hyper-V

I finally figured out why Battlefield 6 was running terribly on my rig (Ryzen 9 7950X3D + RTX 5080 + 32 GB DDR5).
Turns out it was Hyper-V messing with Windows’ CPU scheduler.

Here’s what was happening and how I fixed it 👇

🧠 The problem

• With Hyper-V enabled, Windows treats CPU cores as virtual processors.
• On AMD X3D chips, this breaks the 3D V-Cache scheduler that’s supposed to keep games on the cached CCD.
• As a result, Battlefield 6 randomly jumped between CCDs → stutters, uneven frametimes, and unstable clocks.

⚙️ The fix

• I disabled Hyper-V (and related virtualization services like Windows Subsystem for Linux / Windows Sandbox / Memory Integrity).
• After rebooting, Windows went back to the native AMD scheduler behavior — the game now locks to the V-Cache CCD correctly.
• FPS and frametimes became perfectly smooth again.

✅ Result

• Stable 1%/0.1% lows
• No CCD switching mid-game
• Smooth gameplay, consistent clocks, lower CPU temps

💬 TL;DR

If you have a Ryzen X3D CPU and weird stuttering or inconsistent performance in Battlefield 6 (or other games), check if Hyper-V is enabled.
Disable it, reboot, and you might instantly fix your performance issues.

Also I customised my user.cfg with the usual Processor commands, maybe that helps too in combination until DICE fixes it.
